The raw material for artificial turf is polyethylene or polypropylene, both of which are electrically insulating, but why does it still generate static electricity? In fact, the better the insulating properties of the material, the more likely it is to generate static electricity.
The first thing we need to know is how static electricity is generated. Any two objects of different materials coming into contact and then separated can generate static electricity, and the common method of generating static electricity is by friction.
Because the friction between objects will generate static electricity, people and the lawn generated by the current is electrically insulating artificial turf to resist isolation, can not be normal flow into the earth, then, the negative current will be around the grass wire attachment, once encountered can produce positive friction, it will occur frictional electricity.
The generation of static electricity
1、There are transformers near the construction site and high voltage lines overhead.
2, the site itself does not do effective grounding protection measures or protection measures are not qualified.
3, construction order is wrong (the correct order: first facility grounding, then paving lawn)
So, about the artificial turf site generated static electricity how to deal with it?
1. Ensure that the working environment has a grounding wire: weld the wiring copper strip to the bottom of the post-added metal parts, lead from the bottom of the lawn and connect it to the PE terminal (equipotential coupling terminal) of the original facility.
2. If there is still static electricity accumulation and the environmental humidity is less than 30%, it is recommended to spray the anti-static agent once, which is non-toxic, harmless and a green product. (Antistatic agent: water = 1:100, 1Kg of pure antistatic agent prepared mixture can be sprayed single time area of 500-1000m2).
There are two main situations where colour differences occur.
1, different grass silk, lawn within the batch, between the batch caused by the colour difference (normal batch difference); curved silk curvature inconsistent resulting in visual colour difference.
2, patterns and large goods, large goods and large goods between the winding direction is not consistent; observation site direction, light, angle caused by different visual colour difference.
Therefore, we need to do the following two things.
1. Determine the consistent direction of winding between large goods and large goods, patterns and large goods. (per roll of lawn); curvature inconsistencies can be recovered in the sun for a few hours in sunny weather at temperatures above 25 degrees.
2. Confirm if the same batch number as the previous batch when replenishing. Different batches of lawn cannot be used on the same site; keep the same light and viewing angle for comparison.
